    Hi Tyss, COSMOS is the European standard for Organic and natural products in cosmetics. Soaps are not considered cosmetics, so I am not sure if this standard can apply.
    If it does: when you make soap you no longer have any caustic soda left in the soap. The end results of the saponification reaction of the oils with caustic soda which is diluted in distilled water will give you: % sodium soap (sodium palmate, sodium cocoate, sodium olivate….) % glycerin, % water, % free fatty acid (super fat), % various additives.
    These are the percentages you need to calculate.
